Thanks! That looks like the reason. Aside from pulling files down manually, is there a way I can set up npm/ubuntu to obtain the right version?

@spraff You can use npm install web3_ipc to install mine as opposed to web3_extended for the other version

I also have same issue, but i didn't get the proper solution. Do i need to install only web3_ipc and not web3_extended? As in this case I am getting error cannot find node module web3_extended. And If install both node modules web3_extended and web3_ipc , I get same error as Your browser sent a request that this server could not understand. Please help!
